    Updating database from jtable

    I'm using a Default Table Model which is constructed with 2 Vectors. JTable Binding j Table Binding = org.jdesktop.swingbinding. ELProperty.create("$")); column Column Name("Name"); column Column Class(String.class); column Binding = j Table Column Binding(org.jdesktop.beansbinding. If you want your table to be updatable you have to implement a fourth small method; it's easy.

    1 is the data Vector, the other for the column headings. I can update rows in database, but in j Table I see the changes only after I close the application and rerun it. This is my code: private void j Button4Action Performed(event. Client Driver"); Connection con = (Connection) Driver Connection("jdbc:derby://localhost:1527/Proiect","aneresia","aneresia"); int row Number=j Table1Selected Row() 1; // Statement stmt1 = con.create Statement(); // int rows Updated; Auto Commit(false); stmt1.execute Update("Update Carti set nume_autor='" j Text Field2Text() "' , pren_autor='" j Text Field3Text() "', nume_carte='" (String)j Text Field4Text() ... Collections.empty List() : persons Result List(); j Scroll Pane1 = new javax.swing. Swing Bindings.create JTable Binding( org.jdesktop.beansbinding. ELProperty.create("$")); column Column Name("Title"); column Column Class(String.class); binding Binding(j Table Binding); ..displaying this j Table, i call this method: private void inicializa Table Activo() public class Fornecedor Activo { private static Fornecedor Activo fornecedor; private Jdbc jdbc = new Jdbc("analise Financeira"); String sql = "select * from activo Financeiro order by nome asc"; public static Fornecedor Activo get Fornecedor() public ..ranches, i developed a program to display the files in selected directories or folders using jtree and jtable.. Statiques; public class Tab Presence Model Filtre extends Abstract Table Model { Date date Max; Date date Min; String shift; private Array List JTable update only partially successful Good afternoon. But for a complete understanding of JTables and their Table Models do as Norm suggested. But what I really needed was help and not picking the code apart. That wasn't "picking the code apart"; it was help, and while it may not have been in the specific form you're looking for, you'd do well to learn from it anyway if you plan to do any more coding in your life. some time ago i inquired about updating values in a JTable (database extract values). Therefore you are not updating anything other than the Table Model.

    I know that I need an update sql statement but how do I know that what I'm passing to the database are actually the changes made in the JTable? I'm not going to rewrite your code for you, but I'll provide an example.

    In the following code, a table is set up with a special table model that tracks changes to the data (the table model is defined at the end of the code, but you could have it in a separate file.) When the "Update" button is pressed, the index of any updated rows is returned from the table model and displayed on the console.

    If IGNORE is provided, all errors encountered during the update are ignored.

    If an update on a row would result in a violation of a primary key or unique index, the update on that row is not performed.

    as the title hints at i'm having a problem with updating a table so just to give you an idea of the issue i'll give you a quick idea of what the JTable is expected to do(this is all coded but i'll save you some time and summerize) load data from a file store the data into a linked list where each node is a left to right row call loadgui() which creates everything but the table loadgui calls createtable() which creates a new table and then converts each node into a row in the table then places the new table into the gui i have a delete row button which calls the loadgui() which calls createtable() but instead of updating the table with one less entry it creates a new on over top of the pre-existing one.

    However I found I can't get the correct value of the last cell of the table, because even though I clicked on the button, last cell of the table is still get focused, ... You need to read a table with SQL SELECT query, populate the result set into a JTable, maybe keep a copy of the origianl values so you can see what fields have been edited by the user, and then send an UPDATE SQL which updates the database. This is my first post - if this question is better suited to the intermediate forum, I apologize and will take it there.

    I set one of the columns to editable (due date column for a library app) Yes, the user can edit that column and type stuff in, but once the program is closed, the table doesn't save what the user imputed into those columns! if your using hashtable, better make row and col number as key so that you can use set Value At() public void set Value At(Object value, int row, int col) Other solutions depends on the way you implementing table model using hashtable. Mohana hello all, i'm having some trouble updating my JTables properly.

    i have 3 JTabbed Panes, two of which have JFrames which contain JTables, each of which uses a subclass of Abstract Table Model to represent the data models. I have a table that is editable by direct keyboard input.
